DMCAing Google has always seemed a bit pointless. If I'm ever looking for a pirate copy of something I automatically scroll to the bottom of the page where you can read the DMCA complaints that helpfully compile a list of pirate copies.
Everything is redacted by default. You can obtain the full DMCA reports but it requires you to fill in your email on each of them and request them. It’s not impossible but definitely a little more involved than just “read[ing] the DMCA complaints”
